The end of used games?

I just read IGN's article on Sony's new PSN Pass program. I am wondering when, rather than if, all games are going to have some sort of activation code or all games are sold online through a virtual store and are therefore attached permanently to your account. It makes sense because the game industry struggles already to make the amazing games we love. More work and less pay seems to be the future for game developers. What do you guys think the solution to this is? Is it making so everyone has to pay full price? Is it providing some sort of subscription? I already struggle to buy all the games I want to play. I'm no expert in business. I'm hoping the industry comes up with a solution that is feasible and I'm sure they will. What are you guys' thoughts?
